Abstract
A device for testing the inflation state of an cold gas inflator for an airbag has a gas reservoir that is filled with gas at a high pressure, in particular an inert gas. Oscillations of frequencies varying within a particular frequency range are generated at the filled gas reservoir and the resonance frequency is measured. The measured resonance frequency is compared by a comparator with a resonance frequency which was determined at the gas reservoir filled with the desired pressure.
